RADIO RECEPTION
Usually, a problem with radio reception does
not mean there is a problem with your radio —
it is just the normal result of conditions outside
the vehicle.
For example, nearby buildings and terrain
can interfere with FM reception. Power lines
or telephone wires can interfere with AM sig-
nals. And of course, radio signals have a lim-
ited range. The farther you are from a station,
the weaker its signal will be. In addition, re-
ception conditions change constantly as your
vehicle moves.
Here are some common reception problems
that probably do not indicate a problem with
your radio:
FM
Fading and drifting stations — Generally, the
effective range of FM is about 40 km (25
miles). Once outside this range, you may no-
tice fading and drifting, which increase with
the distance from the radio transmitter. They
are often accompanied by distortion.
Multi-path — FM signals are reflective, mak-
ing it possible for two signals to reach your an-
tenna at the same time. If this happens, the
signals will cancel each other out, causing a
momentary flutter or loss of reception.
Static and fluttering — These occur when sig-
nals are blocked by buildings, trees, or other
large objects. Increasing the bass level may
reduce static and fluttering.
